Question

我迁移到Androidx，但迁移后出现以下错误：

 Caused by: android.view.InflateException: Binary XML file line #12: Binary XML file line #2: Error inflating class android.support.design.widget.CoordinatorLayout
 Caused by: android.view.InflateException: Binary XML file line #2: Error inflating class android.support.design.widget.CoordinatorLayout

我研究了所有资源并迁移到Androidx，但是仍然存在很多问题。有人能帮我吗？我将在下面的代码部分中发布。

Answer 1

在XML文件中，替换 androidx.appcompat.widget.RecyclerView 与： androidx.recyclerview.widget.RecyclerView

Answer 2

确保在您的活动和片段中没有在导入部分中引用旧的支持库。确保所有布局也都没有使用ols支持小部件。

Answer 3

应用似乎正在尝试从支持库（而非androidx库）中充实android.support.design.widget.CoordinatorLayout。尝试执行以下操作，并检查其是否有效。

执行clean and build您的应用。
尝试Invalidate Cache and Restart。

还要确保您没有在其他任何地方使用支持库中的协调器布局。

Answer 4

在gradle.properties文件中添加这两行，以自动将现有项目迁移到Androix。

android.useAndroidX=true
android.enableJetifier=true

更多信息在这里-> https://developer.android.com/jetpack/androidx/migrate

这将自动解决您的问题。

Answer 5

您可能会在某些xml布局文件中引用android.support.design.widget.CoordinatorLayout。

按[CTRL] + [SHIFT] + [F]或转到编辑/查找/在路径中查找，然后仅搜索“ android.support.design.widget.CoordinatorLayout”并将其替换带有“ androidx.coordinatorlayout.widget.CoordinatorLayout”。

您可以使用[CTRL] + [SHIFT] + [R] 或在路径中编辑/查找/替换来立即替换所有匹配项。

Answer 6

只需转到XML文件（在`res / layout中）并替换

androidx.appcompat.widget.RecyclerView

具有：

androidx.recyclerview.widget.RecyclerView

Answer 7

您必须将所有android.support.design类替换为 AndroidX 的新类。这是新旧类之间的对应关系的链接：

更多信息，您可以阅读指南，了解如何迁移到 AndroidX ：

https://developer.android.com/jetpack/androidx/migrate

Answer 8

编辑->查找->在路径中查找 全部替换以下

(.) msum (map return) -> android.support.v7.widget.CardView
androidx.cardview.widget.CardView -> android.support.design.widget.TextInputLayout
com.google.android.material.textfield.TextInputLayout -> android.support.v4.widget.NestedScrollView
androidx.core.widget.NestedScrollView -> android.support.v4.view.ViewPager
androidx.viewpager.widget.ViewPager -> androidx.constraintlayout.ConstraintLayout
androidx.constraintlayout.widget.ConstraintLayout -> androidx.core.view.ViewPager
androidx.viewpager.widget.ViewPager -> androidx.core.widget.SwipeRefreshLayout
androidx.swiperefreshlayout.widget.SwipeRefreshLayout -> android.support.design.widget.AppBarLayout
com.google.android.material.appbar.AppBarLayout -> android.support.design.widget.CollapsingToolbarLayout
com.google.android.material.appbar.CollapsingToolbarLayout -> android.support.v7.widget.Toolbar

迁移到androidx后错误放大类
